Answer:
75.062c
Step-by-step explanation:
To find the missing side use pythagorean theorem
So 
Solve for b, b= 6.021
To find the area use
bh
So
(6.021+19)(6)= area
And you get 75.062
Answer:
It's 4x - 8 + 4y
Step-by-step explanation:
4(x-2+y)
4 (x) = 4x
4 (2) = 8
4 (y) = 4y
4x - 8 + 4y
Answer:
surface area: 7241.25
Step-by-step explanation:
using this formula for surface area of cyclinder: 2πrh+2π
diameter = 2r --> 39.2 = 2r
so r= 19.6
